DB25 DB25JLPS3V2— lug 20mm

The lug width of the De Bethune DB25 DB25JLPS3V2 is 20 mm. This measurement refers to the distance between the two horizontal pins that attach the strap to the case, not the overall dial width. It is essential to verify this measurement before ordering a strap, as an incorrect lug width will not fit properly.

For a platinum case, alligator leather with natural tanning is the primary choice: the pronounced grain introduces a biological element that elegantly contrasts with the cold metallurgical geometry. Alternatively, vegetable-tanned calf offers patina that ages naturally over time, aligning with the patina platinum develops. For sportier contexts, a high-density NATO fabric in light grey or navy blue provides versatility without aesthetic compromise.

The change occurs via two replacement spring bars that insert into the lug pins. It is recommended to use a dedicated spring bar tool to avoid scratches on the platinum case. Position the spring bar in the lower crescent of the lug, press downward to release the spring, then remove the old strap and insert the new one. Casati Milano provides specialised assistance for this operation at their appointment-based atelier.

Yes, provided the lug width is exactly 20 mm. Milano Straps offers artisanal compatible straps manufactured in alligator, calf, shell cordovan and technical fabrics. It is important to verify that the strap is free of curved spring bars or eccentric diameters, which could cause misalignment on the sculptural case of the DB25.

Lifespan depends on intensity of use, climate and material chosen. High-quality alligator with vegetable tanning typically lasts 3–5 years of daily wear before replacement, developing desirable patina in the meantime. Calf leather tends to wear more rapidly (2–4 years), whilst shell cordovan, if properly maintained, can exceed 7–8 years. NATO fabrics, less sensitive to wear, guarantee superior longevity unless fibre wear becomes apparent.
